POLLUTION AND OZONE LAYER Ozone is a condensed form of Oxygen. It has three atoms of Oxy-gen instead of two and has a faint blue colour with pungent odour. In industries it is used in deodorization, oxidation and bleaching and is gen­erated by a silent electric discharge in ordinary Oxygen. Thus it is useful in this way. It is very useful in saving life from sun radiation. It actually forms an umbrella over the earth. It is concentrated generally 30 km above the surface of earth. It is generated there by the interaction of high energy radiation of the sun on the oxygen in the atmosphere. Its concetration is only 10 parts per million parts of air. Still it stops sun radia­tion to penetrate the earth. If there is a pollution of ozone i.e. if the ozone layer is disturbed the sun radiation would attack human life, animal and plant life. The ultra violet rays would eat all life on earth. A one per cent reduction of ozone layer would mean 4 to 8 per cent increase of skin cancer among people having light coloured skin. With an increase of 22 per cent cancer among men and 17 per cent women in Australia the Northern America was rather awake....
